Glass/polyvinylbutyral laminates having directional surface patterns and a process for preparing same |
| 摘要 |
<p>De-airing of PVB/glass laminates can be improved, while haze in the pre-press is minimized and sleep time reduced as a result using a PVB sheet having a roughened surface with directionality. A roughened surface with a washboard pattern that is useful in this regard can be obtained by varying certain conditions of a melt-fracture extrusion process.</p> |
